Hydraulically driven forklift

A hydraulically driven forklift having a vehicle body provided with a pair of right and left front wheels and a pair of right and left rear wheels, and a mast and forks disposed at a front end of the vehicle body, comprising:

• the front wheels respectively operably connected to drive shafts of hydraulic motors attached to the vehicle body,
• the vehicle body provided with two hydraulic pumps driven by an engine,
• each hydraulic pump corresponding to and being connected to one of the hydraulic motors, and
• the rear wheels provided to be turnable around vertical axes with respect to the vehicle body,
• hydraulic motor flow rate being decreased according to turning angles of rear wheels during a turn, thereby to reduce overall traveling speed of the forklift.

• each hydraulic pump corresponding to and being connected to one of the hydraulic motors, and
• the rear wheels provided to be turnable around vertical axes with respect to the vehicle body,
• wherein the hydraulic pumps are electrically controlled and arranged to control swash plate angles based on a travel instruction signal from a controller, the arrangement being such that the travel instruction signal is emitted from the controller to the hydraulic pumps by feeding to the controller a detection signal from a detector for detecting an amount of travel of a brake pedal.
